Boards in 2 GitHub repositories, designed in KiCad, that use the MCP4451-104E/ST by Microchip Technology (-40℃~+125℃ 100kHz 100kΩ 2.5uA 2.7V~5.5V 257 4 50ppm/℃ 75Ω I2C Linear Power-on reset RAM ±20% TSSOP-20 Digital Potentiometers ROHS). See how each wires it, with its parts, size, README and files; the MCP4451-104E/ST’s symbol, footprint and pinout are on its own page.


AaronDoubert/quadcopter-pid-boards
Analog PID flight controller for a 5" quadcopter: roll, pitch and yaw loops built from op-amps and trimpots, fed by an MPU-6050 through a small ATtiny/DAC "shim", driving a 4in1 ESC. Designed in KiCad 10.
